Abstract
Purpose of research: to study morphologic and functional changes in the application of various patch tissues in the inclusion into the arterial flow. Material and methods. Various patch tissues were studied in experiments: polytetrafluoroethylene prosthesis was used as an artificial tissue, a major saphenous vein was used as a superficial autologous vein, superficial femoral vein was used as a deep vein. Results and discussion. Data about wall thickness, area of endothelial nuclei and vascularization of various plastic materials in arterial flow were obtained. Conclusion. The femoral vein possesses more stable morphological and functional properties in comparison with the major safenous vein and is less prone to develop fibrosis then vascular prosthesis. It makes the femoral vein a plastic material with good prospects for brachiocephalic reconstructive surgery.
